How Do You Compute constrainnts that Avoid Boilover?

[hollerg]

How does one set the constraints (startup or operation) to avoid bumping or boilover of an evaporator or batch stripper, especially at vacuum.

What correlations for pressure change and or heat flux would be used to establish prudent rate of change constraints using the physical properties of the fluid and geometry of the vessel?

Thanks for considering my question.
